Abstract
A film cassette comprises a spool supported within a cassette shell for rotation about an axis to thrust a filmstrip coiled about the spool to the exterior of the shell whether the filmstrip is unexposed or is only partly exposed, and a film exposure status indicator supported for rotation within the shell about the axis from an unexposed position to respective partly exposed and fully exposed positions for providing visible indications that the filmstrip is only partly exposed or is substantially exposed. According to the invention, the spool and the status indicator are fixed coaxially to each other. The spool has three spaced detents arranged at separate locations for respective engagement to lock the indicator in its unexposed, partly exposed and fully exposed positions. The shell has an end cap including a locking pawl normally urged to individually engage any one of the detents, but which can be moved to disengage any one of the detents by a suitable device in a camera.
